Research Assistant/Engineer

Key Projects:

. Part of engineering consultants that designed, experimentally tested

and numerically validated the new Avancon Composite Bridge, Bex,

Switzerland (10, 2012), the first FRP-balsa composite sandwich bridge

in Switzerland.

. Proposed and investigated (base on experiments and numerical methods)

a new innovative complex core system to be used as a new model for

composite sandwich bridge decks.

. Micromechanical modeling and characterization of the shear properties

of balsa wood as a core material.

. Failure and fracture analysis of Steel, FRP composites and balsa core

materials.

Achievements:

. Successfully characterized Balsa wood based on its shear properties as

a core material for composite sandwich bridge decks.

. Successfully developed analytical models to predict the bending

behavior of sandwich beams

. Successfully developed analytical models to predict stress

concentrations at joints in sandwich beams.

. Proposed reinforcing sandwich bridge decks with FRP-laminate arch

resulting in deck thickness reduction.

. Proposed timber inserts into bridge decks resulting in girder flange

thickness reduction and cost saving

Conpro Limited, Kumasi, Ghana

08/2006-10/2007

Civil/Structural Engineer

Key Projects:

. Designed and supervised construction of industrial, commercial and multi-

storey residential complexes with limited budgetary resources.

Concurrently managed 5 engineering technicians and 4 site engineers.

. Designed and supervised the construction of large hall/theatre hosting up

to 5000 people.

Achievements:

. Suggested using cross beams instead of intermediate columns which

improved floor clearance, reduced formwork and overall project cost

by15%.

. Delivered projects within budget, on time and on schedule.
